Technical Field
[0001] The utility model belongs to the technical field of packaging, and in particular relates to a packaging structure for hazardous chemicals. Background Art
[0002] Dangerous chemical packaging is mainly used to hold dangerous chemicals and ensure their safe transportation. Dangerous chemical packaging can prevent dangerous chemicals from deteriorating or reacting due to adverse climate or environmental influences; reduce direct external forces during transportation; prevent dangerous chemicals from leaking, volatilizing and improper contact, and facilitate loading and unloading, transportation, etc. Dangerous chemical packaging can be divided into general packaging, gas cylinders, special packaging for explosives, radioactive materials and corrosive materials according to the types of dangerous goods. Among them, the gas cylinder packaging structure is widely used due to its many advantages such as small size, compact structure, light carrying and convenient use. However, the internal pressure of the gas cylinder is high, the storage energy is large, and the process requirements of the bottle body are extremely strict when storing high-pressure gas for a long time. In the current market, gas cylinder leakage accidents occur from time to time. In order to prevent such safety accidents, the existing methods mostly rely on dangerous chemical sensors for early warning to ensure the safety of workers. However, this method also leads to a significant increase in the cost of use. In view of this, the utility model proposes an improved dangerous chemical packaging structure, which aims to enhance the safety of the gas cylinder packaging structure, and at the same time can quickly identify whether the gas cylinder is leaking, thereby effectively reducing the cost of use.

In order to facilitate the observation of the situation inside the reaction layer 5, a transparent observation window 6 is also arranged on the side wall of the outer bottle, so that the user can intuitively understand the situation inside the reaction layer 5.
